P2 - High performance decanter centrifuge for process industries - Alfa Laval - #1

Text version of the page

Application Alfa Laval P2 decanter centrifuges are designed for slurries that are often extremely errosive and aggressive. The P2 range provides the most cost-effective, high-performance solution combined with the lowest power consumption and life cycle costs available. Design Alfa Laval designed the P2 range of decanter centrifuges with a focus on performance, easy access, reliability and low noise levels. The rotating assembly is supported on a compact welded box beam frame with main bearings at both ends. The in-line motor is flanged or foot-mounted on the decanter with brackets for belt tension adjustment. The bowl is driven at the conical end by an electric motor using a V-belt transmission. The bowl, conveyor, casing, inlet tube, outlets and other parts that come into contact with the process media are made of AISI 316 and Duplex stainless steel. High-performance decanter centrifuge for process industries P2 decanter centrifuge range Operating principles Separation takes place in a horizontal cylindrical bowl equipped with a scroll conveyor. The product is fed into the bowl through a stationary inlet tube and is then smoothly accelerated in a full flow feed zone design. Centrifugal force deposits the solids on the inner surface of the bowl. The conveyor rotates in the same direction as the bowl, but at a different speed, thus moving the solids towards the conical end of the bowl. The solids leave the bowl through the solids discharge openings into the casing. Separation takes place throughout the entire length of the cylindrical part of the bowl, and the clarified liquid leaves the bowl by flowing over adjustable plate dams into the casing.
